I had my system freeze when doing a pull from Linus's repo. Since then, every 
pull results in the following errors:

~> git pull
error: unable to resolve reference refs/tags/v3.1-rc8: Success
 From git://github.com/torvalds/linux
  ! [new tag]         v3.1-rc8   -> v3.1-rc8  (unable to update local ref)

Any suggestions on how to fix this error?

Thanks,

Larry
